I love a lot of what this book is about, between the concept and execution it is a superb exploration of a lot of ideas. The central conflict, however, feels more like a contrived horror film plot than a carefully crafted sci-fi coming of age story. If the antagonists had been more nuanced I think this would easily be a 5-star book for me, but as it's closer to its YA roots (a little too good/evil with not enough nuance between), I wanted a little more than it gave.

That said, it does have some marvellous grey areas that it dips toes and pokes fingers into. I hope some of these are more carefully explored in the sequels - which I will definitely be looking for.
